Position Description Background of thesis project
Reducing fuel consumption and CO2 emission is one of the biggest concerns of the automotive industry.
Fuel efficiency is continuously being improved thanks to hardware development but also software
improvement. The purpose of the master thesis is to develop methods for optimization of shift strategies
for bus automatic gearboxes.
Suitable background
Knowledge about powertrain components and systems
Knowledge and experience with Matlab/Simulink
Experience in optimization algorithms is a plus
Description of thesis work
Automatic gearboxes used in Volvo busses are provided by vendor suppliers. The gearshift strategy is
customized for each bus/application. It is adjusted by performing physical testing on prototype buses
and this work is resource consuming. This master thesis is about investigating the possibility to
predefine shift points for our automatic gearboxes in order to save time during the shift strategy
adjustment process and achieve increased fuel efficiency of the complete powertrain. This will be done
thanks to optimization methods to be developed and applied to our driveline simulation models based on
Matlab & Simulink. The optimization methods will have fuel consumption and performance criteria as
targets and noise/vibration and component physical limitations as constraints.
